Missed Call Cost Calculator

Estimate the potential revenue behind missed new-prospect calls, allowing for the follow-up you already do.

Starting values are illustrative assumptions, not industry benchmarks or measured Topher AI results. Replace them with your own figures.

200
Count each eligible new prospect once. Exclude repeat calls, existing customers, spam, and inquiries you cannot serve.
25%
Use call logs where available. Include eligible prospects whose first call goes unanswered or to voicemail.
50%
Of the initially missed prospects, how many reconnect through callbacks, repeat contact, or other existing follow-up? These are excluded from the remaining opportunity.
10%
Of the remaining prospects, the share you assume would become customers if reached. Your measured rate for comparable prospects can inform this assumption.
$3,000
Revenue in USD from one initial job or engagement. Exclude lifetime value and repeat business; this is revenue before costs, not profit.
50%
What share of the prospects still unrecovered could an improved process reach? This is your scenario assumption, not a forecast of Topher AI performance.
Potential revenue from one month's unrecovered prospects
$7,500

Assumes all remaining prospects are reached and convert at your chosen rate. Initial job or engagement revenue may arrive later; this is not monthly cash flow.

All results refer to the same month's group of prospects. Estimates may include fractions of a prospect or customer; displayed figures are rounded.

How the calculation works

Start with one month's eligible new prospects, and subtract those your existing follow-up already reaches. The remaining opportunity uses your conversion and initial-revenue assumptions:

missed prospects = new prospects × missed %
unrecovered = missed prospects × (1 − existing follow-up %)
potential customers = unrecovered × conversion %
potential initial revenue = potential customers × initial job value
recovery scenario revenue = potential initial revenue × additional recovery %

Percentages are divided by 100 for the calculation. For example, 200 new prospects × 25% initially missed × 50% still unrecovered = 25 prospects. At an assumed 10% conversion and $3,000 initial job value, that represents $7,500 in potential initial revenue. Reaching an additional 50% of those prospects gives a $3,750 scenario using the same conversion assumption.

These are estimates for a monthly group of prospects, not measured losses or guaranteed recoveries. The calculation does not predict when revenue arrives, whether you have capacity to serve the customers, or profit after delivery costs and service fees.

How to choose your inputs

Review the same reporting period across your call logs and customer records:

  • Count eligible prospects once. Separate new inquiries from repeat attempts, existing-customer calls, and spam. If you cannot identify missed callers, label your estimate as an assumption.
  • Check initial handling. Include unanswered eligible inquiries during working hours, after hours, and when lines are busy.
  • Credit your current follow-up. Match missed inquiries to callbacks and later contact before treating them as unrecovered.
  • Use comparable outcomes. Review your conversion rate and initial job revenue for similar prospects, allowing enough time for them to become customers.

Try several recovery and conversion assumptions to see how sensitive the result is. An answered call alone does not establish a sale.

What to do with the number

Use the result to decide what to measure in a trial: additional prospects reached, qualified inquiries, and resulting customers. Compare the actual incremental profit after delivery costs with the full cost of the service. A revenue estimate alone cannot establish whether a subscription pays for itself.
